CONTAINER FOR SPOOLS 0F CORD Filed Jan. 6, 1964 2 Sheets-Sheet 2 INVENTOR ALFRED E. BOGZEH 3,193,179 CONTAINER FOR SPQOLS OF CORD Alfred E. Bogren, Milford, N.J., assignor to Continental Can Company, Inc., New York, N .Y., a corporation of New York Filed Jan. 6, 1964, Bar. No. 335,756 Claims. (Cl. 22951) This invention relates to a unitized package comprising a plurality of containers and more particularly relates to a corrugated, dual container for the packaging of spools of cord of the type used in modern baling machines.

In modern automatic baling machines it is customary to use at least two balls of baling twine or cord. While one of the balls of twine is being used, the other ball of twine constitutes a reserve supply. These balls have usually been tied together by attaching the trailing end of the first ballto the leading end of the second ball. In order to reduce the possibility of the ball of twine collapsing and becoming tangled, it has previously been customary to wrap the ball of twine with a layer of wrapping paper. Quite frequently, this paper becomes damaged or is simply inadequate to suitably support the ball of twine.

It is an object of the present invention to provide a container for baling twine or cord, which container is I closure cap which is adapted to cover an adjacent pair of containers, said cap comprising a first cover section and a second cover section, the first cover section and the second cover section being joined along a transverse center line, means attached to theclosure cap along the periphery thereof for connecting the closure cap to the containers, and a removable section which extends on opposite sides. of the transverse center line and is adapted to be torn from the closure cap such that the adjacent pair of containers are separated from each other.

Another object of this invention is to provide a closure @cap, of the type described above, wherein the removable section has opposite ends thereof which are located adjacent to the geometrical center of each of the cover sections, the opposite ends being defined by cut lines and the removable section being further defined by weakening lines which diverge from each cut line and meet at the transverse center line.

Another object of this invention is to provide a closure cap of the type described above wherein a reinforcing tape extends on opposite sides of the transverse center line, and the tape includes a plurality of fibers which extend diagonally of the transverse center line in at least two directions whereby the reinforcing tape is unlikely to rupture along the transverse center line.

Another object of this invention is to provide a pair of containers and a pair of closure caps forming a package which is particularly adapted to be used with balls of baling twine, the containers each being comprised of an upright tubular member adapted to receive a ball of twine, each of the closure caps being comprised of a pair of cover sections for closing the tubular members, the cover sections being symmetrical about and joined together along a transverse center line at a reduced por- United States Patent 0 tion of the respective closure cap, each of the closure caps having a removable section thereof which extends on opposite sides of the transverse center line and terminates adjacent the geometrical center of each cover section for providing an opening in the top and bottom of each of the containers, the top opening providing an inspection slot for viewing the contents of the container, and the bottom opening providing means for locating and positioning the end of the outer course of the ball of twine.

With the above and other objects in View that will hereinafter appear, the nature of the invention will be more clearly understood by reference to the following detailed description, the appended claimed subject matter and the several views illustrated in the accompanying drawings.

In the drawings:

FIGURE 1 is a perspective view of the present invention and illustrates a pair of upright tubular containers which are joined together by a unitary closure cap.

FIGURE 2 is a fragmentary perspective view, similar to FIGURE 1, and illustrates the manner in which a removable section of the closure cap is torn therefrom so as to separate the containers from each other and to reveal the contents contained therein.

FIGURE 3 is an enlarged vertical sectional view, taken on line 33 of FIGURE 1, and illustrates the tubular members as being constructed of corrugated board having the corrugated flutes thereof disposed horizontally.

FIGURE 4 is an enlarged horizontal sectional view, taken on line 44 of FIGURE 1, showing the construction of the upright tubular members and illustrating the outline of a removable section in the bottom closure cap.

FIGURE 5 is a plan view of the inside surface of a closure cap prior to slitting and creasing thereof and shows a reinforcing tape having the fibers thereof extending diagonally across a transverse center line of the closure cap.

FIGURE 6 is a plan view of a two-piece blank for forming one tubular member and one closure cap in accordance with the present invention.

Referring to the drawings in detail, there is illustrated in FIGURE 1 a package, generally indicated by the numeral 10, which package includes a pair of upright tubular members 1-1 and 12 for forming a pair of containers 13 and 14. The containers 1'3 and 14 are closed at the top end thereof by an upper closure cap, generally indicated by the numeral 15, while the bottom end of the containers 13 and 14 are closed by an identical closure cap, generally indicated by the numeral 16.

The tubular members 11 and 12 are identical to each oth r and are constructed from a blank, generally indicated by the numeral 20, as is shown in FIGURE 6. The blank 20 is rectangular and is provided with a plurality of parallel fold lines each extending the full width of the blank and spaced so as to define a plurality of center panels 21, an end panel 22 and a glue flap 23. As is shown in FIGURE 6, it is preferable that the end panel 22 be slightly less in width than each of the panels 21. Prior to erecting the blank 20 to form a tubular member 11 or 12, it is desirable to crush the glue flap 23 and a like area of the end panel 22 such that when the glue flap 23 is adhesively secured to the end panel 22 a smooth joint is formed as is shown at 24 in FIG- URE 4. The blank 20 may be cut from paperboard, heavy paper, plastic or other similar flexible material, but it is preferred that the blank 20 be formed of corrugated cardboard having the fiutes 25 aligned horizontally, as is shown in FIGURE 3.

The closure caps 15 and 16 are formed from a blank 26, as is shown in FIGURE 5.
